More than 100 schools in England are grappling with an urgent problem due to structural concerns, following the dramatic closure of buildings constructed with reinforced autoclaved aerated concrete (RAAC). But while this situation presents a significant challenge, it also offers a unique opportunity for the Government and the construction industry to reevaluate their approach to building sustainability and safety, by using low-carbon alternatives that can revolutionise the way we construct our schools and other vital structures writes Tony Sheridan, Group Commercial Director for Cemfree. (pictured) When the government ordered the closure of these schools just days before the autumn term was set to begin, educators, parents, and students found themselves in a state of flux. Alternative learning solutions, including remote learning and temporary classrooms, became the immediate response to the crisis sparking concerns and criticism. While this is an understandable reaction, at the heart of this issue lies the critical importance of responsible design and the correct choice of appropriate construction materials. It underscores the significance of using the right product in the right place and keeping design at the forefront of construction decisions. A crucial consideration should have been the acceptable design life of the structures. If these buildings were originally designed for a 30-year lifespan, it was unrealistic to expect them to last 50 years without issues. If lessons are to be learned we must be mindful of these factors during future design phases and avoid overstretching the longevity of our structures. Another factor to consider as we contemplate rebuilding these educational institutions, is a pressing environmental concern – embodied carbon. The concrete originally used in these structures, and the replacement materials chosen, play a pivotal role in determining their environmental footprints and this is where products such as Alkali-Activated Cementitious Materials (AACMs) can make a huge difference. The issue of embodied carbon, which refers to the total carbon emissions associated with a building material's production, transportation, and installation, cannot be overlooked. When considering replacement materials, it's imperative to assess the environmental impact. Perhaps then it is an opportunity to look at innovative alternatives like AACM’s, which are readily available and have been tested following rigorous research and development programmes? While concrete is undeniably an excellent construction material, its traditional usage has been heavily cement-dependent, contributing to a colossal carbon footprint - 850kgs per tonne as stated by MPA. However, AACMs such as Cemfree are revolutionising the construction landscape, allowing designers to maintain the integrity of concrete while slashing its carbon footprint by up to 85% compared to Portland Cement (PC). Embracing AACMs like Cemfree could catalyse a paradigm shift in the construction of critical structures like schools and hospitals, ushering in a sustainable future. At Cemfree we are committed to ensuring that our products are specified and used correctly, ensuring structural integrity and safety. We work closely with architects, specifiers, contractors, and other stakeholders to guide them through the process from start to finish. Our rigorous approach ensures that Cemfree is not only chosen but also applied appropriately, maximising its environmental benefits. The path to creating safe, ultra-low carbon buildings lies in collaboration. Clients, specifiers, contractors, and material providers must work together to design and construct sustainable structures that are both environmentally friendly and structurally sound. This collaborative effort should span the entire construction process, from initial design to final implementation. The situation with schools in England serves as a pivotal moment, highlighting the importance of responsible design, sustainability, and material selection in construction projects. It offers us a choice – to rebuild with materials that are both resilient and environmentally conscious or continue to use very carbon intensive materials. Could this be the catalyst for a transformation in our commitment to constructing safer, greener, and more sustainable educational spaces for generations to come? As we rebuild our schools, let's not just reconstruct buildings but also reshape the future. The opportunity for change is now, and together, we can pave the way towards a more sustainable tomorrow for our schools and beyond.

Government plans to spend £3.7 billion on dozens of new NHS hospitals has not materialised in the way that some had anticipated, but could that be because budgets are now being spent on offsite construction to deliver hundreds of new buildings, surgical wings and other major refurbishments asks Tony Huggins, managing director of David Bailey Furniture? Offsite construction companies, able to deliver new, ready equipped buildings, sometimes within just 20 weeks, now seem to be filling the demand for essential infrastructure in the NHS. This follows the endorsement by the UK government in 2020 to increase the use of offsite manufacturing in the delivery of healthcare projects. For companies such as David Bailey Furniture, one of the fastest growing manufacturers of specialist furniture and storage solutions for the healthcare sector, it has involved a major change in the way it delivers products for the NHS. By working closely with companies specialising in the offsite construction market, it has been able to produce bespoke products such as reception desks, shelving and fitted furniture to fit precisely into modular buildings that are then transported and finally installed in hospitals and healthcare centres across the country. It is a partnership that starts with precise architectural drawings to allow David Bailey to accurately price and build the furniture, which is then manufactured to exactly fit the predesigned modules. This has allowed the company to deliver a wide range of furniture products across an equally wide range of healthcare applications from x-ray departments to orthopaedic wards, from urology to specialist surgical hubs. Such is the demand for modular solutions that some manufacturers are now anticipating NHS demands and are pre-building units in advance where experience has shown that there is likely to be an order in the near future. Such developments are significantly reducing delivery times still further while allowing the NHS to fulfil its obligation to patients more efficiently. The rise in modular solutions follows the desperate need for new wards and clinical centres, which could be at least two years away using traditional construction techniques. This is in spite of Government promises for up to 40 more hospitals. However, it is now possible with offsite construction and the same ingenuity used to build Nightingale Hospitals during the Covid Pandemic, to deliver those essential new wards and clinics within just a few months. While there is a will by Government and a process in place to build more hospitals it is clear that Covid and the additional strains it has placed on the NHS has made it more difficult to deliver that programme which is why David Bailey Furniture working with its modular construction partners, are convinced that offsite construction offers a real solution to provide the facilities needed by the NHS. This is supported by organisations such as The Chartered Institution of Building Services Engineers (CIBSE) who reported in a recent survey that offsite construction is safer, faster and cheaper. They also added that thanks to offsite construction, 61% of people saw increased productivity, while 47% reported enhanced employee safety. There is a further added bonus that when compared to an equivalent, traditionally-built project, up to 67% less energy is required to produce a modular building and not only is the actual construction of the building 'greener', but the building is also energy- efficient for life. So, it is clear that modern methods of construction are well established as a building technique and can now deliver the highest of construction standards. It is also obvious that offsite construction offers a very real solution to providing those vital healthcare resources and it can be done using highly sustainable materials, greater levels of health and safety and most importantly – it can significantly reduce costs. Yet for all that, offsite construction still only accounts for between 5% to 10% of the industry output. This is compared to around 9% in Germany, 12-15% in Japan and 20% in Sweden, so the potential for growth in this sector is enormous. For David Bailey Furniture, it all means one thing, change, which is why we continue to work closely with our partners in modular construction. We can see that this very much represents a positive step forward in terms of delivering the infrastructure that the NHS so badly needs – so it really is a case of watch this space.

The UK’s first 100% Portland cement free sustainable alternative to standard masonry mortars, developed and manufactured to deliver savings in CO2e emissions of up to 70%, has been launched in the UK by Cemfree, the country’s leading producer and pioneer of ultra-low carbon cementitious technologies and products. This is the second major launch for Cemfree, who 10 years ago unveiled the country’s first cement free binder, a real alternative to Portland cement (PC), responsible for 8% of the world’s CO2e emissions. With industry estimates showing that construction professionals use in excess of some 2.5 million tonnes of cement-based mortar every year, Cemfree believes this new product will give builders, architects and other construction professionals, another major opportunity to help the environment and reduce the risk of Global warming. Cemfree Masonry Mortar is a factory produced designed mortar available directly from Cemfree. It holds appropriate UKCA marking, showing conformity with UK legislation and is fully compliant to BS EN 998-2. Available in premixed bulk or 25KG bags, Cemfree Masonry Mortar performs in a similar way to standard cement-based mortars with the added benefit of significant carbon savings, delivering comparable consistency and curing times and offering excellent workability. “Cemfree Masonry Mortar is a major step forward in terms of reducing the amount of carbon emissions produced by conventional Portland cement-based products,” said Katie Wills, Cemfree Major Accounts Manager. “When used in conjunction with Cemfree concrete blocks, which are now widely available across the UK, the CO2e savings can be even more substantial. This is another major step forward in helping to protect our planet”. Cemfree Masonry Mortar has been launched following extensive development by the Cemfree Technology Team, and independent expert support.  It has been widely accepted and received by the industry during pilot tests to demonstrate the user-friendly nature of the product. The mortar is the latest stage of an ongoing product development programme for Cemfree as it continues to evolve with new technologies and products.  

A new and innovative range of portable ward furniture, especially made to meet the needs of busy hospitals and medical centres, will be officially unveiled by David Bailey, Britain’s fastest growing manufacturer of specialist furniture products, at the Healthcare Estates Conference in Manchester on October 4th. The range which includes a versatile choice of bedside cabinets, wardrobes, storage units and writing desks, has been designed with movement in mind, ready to be wheeled into action to meet any emergency situation or day to day medical requirement. “We have been supplying furniture to Hospitals, NHS Trusts, Private Hospitals and Medical Centres for 40 years,” said Tony Huggins, Operations Manager for David Bailey Furniture, “and in that time have developed a second to none reputation for delivering quality and innovation.” “These have traditionally been fixed storage units or reception, counters and staff bases, but it has been clear for some time that hospitals need a furniture range that is robust and flexible enough to be moved at moment’s notice, particularly in emergency situations, as we have seen in the recent pandemic.” The new range of portable furniture has been designed and manufactured for the benefit of both patients and staff. Every product uses quality proven components such as industry leading “Blum” hinges that will faultlessly open and close – every time – ‘silent run’ casters to allow for quiet easy movement, together with recognised security locks and other features to protect valuables and other essentials. The bedside cabinets offer easy access cupboards for mobile phones and wallets which can be accessed by patients via inbuilt doors at the side of each unit, while the main cupboard has been traditionally kept at the front for larger items. The cabinets together with the rest of the range have been made with a hospital environment in mind and are strong enough to meet the day-to-day challenges of moving beds and trolleys which frequently result in knocks and bumps. The units also meet the highest hygiene standards. The David Bailey Range of portable furniture is now ready for immediate manufacture and can be seen on Stand Number D63 at Manchester Central.

Just before Christmas last year, government gifted a mandate which would see a 30% cut in carbon across all new residential buildings. The updates to Part L of the Building Regulations, which is to do with energy use, Part F for ventilation and the introduction of a new Part O for overheating will reportedly pave the way for a greener built environment. But do the updates go far enough? Ellen Huelin, Associate Director at Whitecode Consulting takes a closer look. Part L updates We have been expecting the changes for some time. This is the biggest update to Part L of the Building Regulations since 2013, where we will see a 30% reduction in carbon in new homes. As highlighted in the updates to Part L, the reduction will be achieved through fabric improvements and carbon saving technologies, i.e., the addition of PV panels or air source heat pumps. The announcements were set out in the Department for Levelling-Up, Housing and Communities (DLUHC)’s response published last month to a public consultation, which ran from January to April 2021 on the Future Buildings Standard. It details interim uplifts to Parts L and F of the Building Regulations and the introduction of Part O. Part L applies to all projects after 15 June 2022, except projects where a building notice has been given. The new regulations will apply to all projects regardless from 15 June 2023. During the consultation an array of options was considered, but they decided to go for a higher uplift that’s not just based on building fabric but carbon saving technologies too. Taking a magnifying glass to the updates, the performance metrics for Part L 2021 include: -         Primary energy target -         CO2 emission target -         Fabric energy efficiency target (FEES – DFEE/TFEE) -         Minimum standards for fabric and fixed building services In many ways the updates to Part L will prepare many companies for the change that will come when the Future Homes and Buildings Standard comes into force in 2025. It is in that sense an important stepping stone. These latest updates to Part L mean that residential buildings built from 2023 are more prepared for the 2025 change. Furthermore, the focus on fabric-first approach and carbon saving technologies will therefore steadily remove dependency on gas boilers which are to be banned in new homes from 2025. Many GLA schemes that the likes of Whitecode Consulting work on are already installing heat pumps instead of gas boilers. The biggest challenge will be ensuring this change happens outside of London. As well as a focus on carbon technologies, a tighter building fabric will need to be achieved in preparation for the Future Homes Standard. The focus here isn’t so much on walls or doors but windows, which lose around 18% of a house’s total heat. To provide a solution to this issue, there is a need for windows to have stronger U-values. We will, then, see triple glazing with a 0.8 U-value expected by 2025. Closer inspection Businesses would do well to start putting these changes into motion as there are new requirements that have to be met. As part of the change and to assure compliance, photographs will be required during the construction of properties to prove correct installation; all plots must be air tested; accredited construction details (ACDs) for thermal bridging will be scrapped; and plot specific approach to transitional arrangements. Taking a closer look at the transitional arrangements is key, as there are details that must be considered. For Part L 2021 the site-wide approach for transitioning will change to a plot/building specific approach. Therefore plots/buildings that do not start within a year of the regulation’s application, even if on the same site, would need to be built to the latest standards. New Part O Another regulation that has been newly introduced is Part O for overheating. Here at Whitecode Consulting we have been performing overheating analysis for many years. Overheating can cause huge discomfort to homeowners and compromise their wellbeing. But, up until now it hasn’t ever been regulated. It is assuring, therefore, to see the introduction of Part O. Previously, TM59 overheating assessments were performed in order to assure compliance with the London Plan. Whilst this rigorous assessment will still be a method of choice on some projects, as it can offer more design flexibility, Part O certainly offers a more simplified, formulaic method which will be desirable on projects. It’s key to look closely at the changes Part O includes. Projects will not, for instance, be able to use internal blinds to comply. Blinds have been continually used in developments to prevent overheating. Now, with the new Part O, schemes will need to include other kinds of shading including external to comply. Whichever route is selected, Whitecode Consulting has the experience and expertise to help clients navigate their chosen path.  All in all, the updates to Part L, Part F and the introduction of Part O are highly welcomed. The updates to Part L in particular will go some way to preparing us for the Future Homes Standard in 2025. The changes, however, are severely overdue and could have gone further, as the reality is that the change has to be done now. Given that we are living in a climate emergency, will the industry be quicker to adopt the change? We’ll have to wait and see. 

Britain might be out of the EU but we still continue to mirror many of their policies - and that particularly applies to climate change, energy savings and sustainability. Fire risk following Grenfell, also remains a major factor and both continue to provide massive challenges for Facility Management companies – especially when it comes to roofing and waterproofing writes Justin Pitman, sales director for Proteus Waterproofing. In spite of these factors, it can be proven that Facility Management professionals prepared to work more closely with suppliers can more easily meet these challenges, get the best quality job and make significant budget savings at the same time. Every building needs a roof, but in today’s green environment it is not enough to simply provide the waterproofing. New levels of insulation are needed to meet updated regulations and in the case of flats there is the added requirement to insulate party walls and other sensitive areas while also taking fire risk into consideration. Insulation levels are 10 times higher than they were 50 years ago.  However, while fire regulations have not changed dramatically in recent years, amendments have been made following the Grenfell tower fire, in particular the ban on the installation of combustible materials in external walls on buildings with a height of 18 metres or more, introduced in October 2019. The Climate Change Act 2008 set in legislation, the UK's approach to tackling and responding to climate change. It introduced the UK’s long-term legally binding 2050 target to reduce greenhouse gas emissions by at least 80% relative to 1990 levels. Since 2012 there has also been a need for all commercial buildings to have EPCs (Energy Performance Certificates). These include buildings used as places of worship and for religious activities. stand-alone buildings of less than 50 m2. industrial sites, workshops and non-residential agricultural buildings with low energy demand including temporary buildings, offices, pubs, shops – the list is endless. The lower the energy use, the more attractive the building to potential end users. With this kind of pressure, it means that the building sector is crucial in achieving Britain’s energy and environmental goals. The good news is that following the introduction of energy performance rules in national building codes and the increased levels of insulation, buildings today consume only half as much as typical structures from the 1980s, but the rules continue to become more stringent and that in turn squeezes budgets. This all adds up to increased pressure and with fire and energy savings setting the agenda, more and more Facility Management professionals are asking companies such as Proteus to help them remove unnecessary costs from all parts of the supply chain. On face value this means offering the most competitive prices on product, but it is a much bigger story than that when set against the much bigger challenge of energy savings and fire risk. In response Proteus has developed a system and product offering to enable them to offer Facility Management professionals a complete roof design package incorporating living roofs (green, blue or brown), solar roof options, safety fall arrest systems and wind uplift calculations alongside their established waterproofing, insulation and fire protection system solutions. This ‘one-stop shop’ approach has allowed the company to provide a more competitive quality to their clients, whilst supporting them through the entire design and installation process. This has resulted in the removal of unnecessary costs and other overheads. In spite of these challenges, upgrading roofing and the waterproofing of other public areas can be incredibly disruptive and unpleasant for residents or office workers who have to remain in the building. There is also the risk of fire when torch on or molten materials are used. The good news is that the development of cold applied, odour free waterproofing systems has significantly reduced this problem and when used in conjunction with plans to increase insulation levels and reduce fire risk, they offer an incredibly cost-effective solution for Facility Management companies. It all adds up to major changes in the way that Facility Management Companies should be dealing with end suppliers. Closer collaboration with everyone involved in the supply chain means that the end user gets the best possible job. It is also the most cost-effective solution for Facility Management professionals when they are prepared to work more closely with suppliers and installers by letting them take the strain in terms of design advice, risk assessment and all the other factors which now dominate the modern construction industry. It is no longer about fighting for the best product price so why let roofing and waterproofing be a challenge when all the expertise you need is on the doorstep.  

Hospitals are the UK’s lifeblood, providing patients across the country with access to specialised medical care and treatment. A cornerstone of their communities, hospitals must undergo routine upgrade and maintenance work in order to ensure they continually deliver to their high standards writes Stacey Lucas from Sontay. King’s College Hospital in south London is a major inner-city hospital managed by King's College Hospital NHS Foundation Trust. As well as being a leading facility for care and treatment, King’s is a large medical hub which is one in a trio of institutions belonging to the King’s College London School of Medicine. The hospital underwent an £80million extension to its existing coronary care unit (CCU) building to provide vital new CCU and isolation room bed space for patients. To ensure these critical areas are controlled and monitored accurately, it was decided that an extensive range of building control peripherals were needed. A myriad of solutions from market-leading specialist Sontay were specified as part of a sophisticated building management system (BMS). Siemsatec, a specialist in BMS design, installation and maintenance was tasked with installing the BMS for the new space. The system needed to give simple control over the extension’s HVAC plant to keep patients comfortable, help streamline the hospital’s budget and offer a healthy environment to patients through effective temperature control. A further consideration was to ensure the hospital could maintain the efficient running of the building and enable energy and cost savings. Working collaboratively with Sontay, Siemsatec undertook full system design and management of the project from start to finish. Siemsatec installed a Trend IQ4 and 963 BMS, along with a range of Sontay solutions, which monitor all of the air handling units as well as the LTHW & CHW plant within the CCU bed spaces. The versatility of Sontay’s solutions means a range of field devices can monitor all aspects of a commercial building. This allows the likes of Siemsatec to select exactly what is required for each application. The Sontay products that were specified included temperature and combined temperature, and humidity sensors to monitor environmental conditions on the wards for patient and staff wellbeing. Immersion and frost thermostats, air and water differential pressure switches, air differential sensors, flow grids, smoke detectors, water detection and thyristor controllers were also specified to monitor the building service equipment. “The new control system ensured the facilities team could manage and monitor the system with ease in order to improve overall efficiency and respond to the needs of both patients and staff in the building,” commented Joe Bailey, Project Manager at Siemsatec. “We decided to use Sontay because of its reliability and the quality of the products. All of the solutions were easy to install and worked well once in place.” This project was extended within a fixed budget and delivered to a tight deadline to ensure the existing CCU unit remained operational. It was essential for the space to remain functional during the renovation process and give patients immediate use of the services. “The prompt delivery Sontay offered really helped us deliver the completed project on time,” continued Joe. Following the installation and completion of the project, the facilities management team at the hospital can now manage, monitor and adapt the control system quickly and easily. They will also ensure the hospital is operating as efficiently as possible and respond to the needs of both patients and staff within the building. The presence of Sontay’s solutions on King’s College Hospital’s new CCU unit will enable a vital medical facility to keep delivering and pioneering treatment for patients for years to come.  

Sustainability has been at the top of the building agenda for many years, with an emphasis on its environmental and economic impact. Such outcomes are of major importance, but it shouldn’t be forgotten that buildings are created for people, and their health and wellbeing should be of the highest priority when it comes to the interior design and workings of offices and other workplaces. Stacey Lucas, Commercial and Marketing Director at Sontay, a market-leader in the manufacture of sensors specifically developed to improve the indoor environment and create healthier, more energy-efficient buildings, looks at how smart sensor technology is being employed for beneficial effect in the places we inhabit most.  Pre-pandemic we reportedly spent more than 90% of our lives indoors whether at home, school or in the workplace. Ventilation, temperature and pressure regulation contribute to maintaining an atmospheric happy medium, which in a work environment helps increase employee contentment, leading to increased productivity and fewer sick days. Building sensors installed as part of an efficient building management system, offer an ingeniously smart and effective way of remotely monitoring indoor conditions, as well as giving property owners more control over energy usage; a benefit that not only helps reduce heating and lighting costs, it facilitates a significant reduction in a building’s carbon footprint. Monitoring key criteria such as relative humidity, CO2 and air quality can also offer vital information on the likelihood of viral transmission in the indoor environment and instruct the BMS to increase ventilation to improve conditions. Their usage could therefore be a factor in driving environmental-initiatives, such as the UK government’s pledge for carbon-neutral status by 2050 as well as building confidence in us returning to office buildings in the future. Sensor solutions Sensors can control a myriad of elements that affect our indoor climate including temperature, which in relation to an office environment is found to be around 22°C. However, relative humidity, if not managed correctly can make a room feel hotter or colder than the actual temperature reading. It can increase the likelihood of bacterial spread at lower levels. A sensor can help overcome these issues by monitoring humidity levels, to ensure an ideal 50% reading is maintained. In terms of air quality, airborne volatile organic compounds (VOC), pollutants which are found in paints and other building materials, are known to have a detrimental effect. The same harmful chemicals are also present in hand sanitisers, aggressive cleaning products and detergents; the demand for which has been unprecedented since the onset of the coronavirus crisis. Air quality sensors are able to measure VOC levels and provide data for when ventilation is needed to maintain occupancy comfort, or the need to take action when a potentially hazardous reading is recorded. Crisis management The COVID-19 pandemic has also focused a lot of attention on the amount of indoor space people should be allowed to share in order to maintain distance and prevent viral spread. A CO2 sensor provides a clear visual indication of when a workplace requires ventilation due to deterioration in the indoor air quality. When we exhale we emit CO2, which if left unchecked in a busy office environment for example, can lead to headaches due to increased discomfort levels. A CO2 sensor with an LED traffic light-style display can help alleviate this issue. When showing green, for instance, the sensor is indicating that a room isn’t over-occupied and the risk to air quality is low. Should the sensor show amber, it’s a sign that windows require opening or fewer people need to be in the room to maintain the same healthy indoors environment. When the sensor turns red it is a call to action, as it indicates there is not enough ventilationin the room. At these last two stages, if a sensor is connected to a building management system, it will activate relevant ventilation. Light level and occupancy sensors offer further relevance to the ongoing pandemic. In relation to the nationwide lockdown, many offices in towns and cities remain empty whilst lights and other energy sources continue to burn unmonitored within the buildings themselves. An estimated 40% of a building’s energy costs are attributed to light usage; therefore, installing a sensor which operates lighting based on a building’s occupancy and interior light levels has financial and environmental benefits. Though relatively small in size, building sensors can have a huge part to play in ensuring properties, particularly workspaces, are managed safely, sustainably and profitably. Like a friend we never knew we had, these smart little devices look out for us when we’re in the office, and look out for the office when we’re at home. They are becoming evermore vital to the way we work today, and in the future.

Insulation within a flooring build-up doesn’t generally gain the same significance as it does in a wall or roof application, but its contribution remains crucial to sealing a building’s thermal envelope. Flooring insulation in a busy commercial setting should have dual purpose. It needs to be strong enough to withstand regular pounding from large footfall or heavy machinery, whilst possessing the thermal properties to help uphold a building’s overall energy performance. Specification consideration The insulation’s specification will depend on a building’s use. In a warehouse or industrial environment where motorised machinery is prevalent, priority will be given to the insulation’s load-bearing capacity when it comes to its selection. This will generally be determined by a structural engineer checking a specified product’s declared load-bearing ability against the weight it will be required to withstand. When it comes to where insulation fits within a commercial flooring build-up, this very much depends on the composition of the floor itself. On a standard sand and cement screed, the insulation will be installed between a damp-proof and a radon membrane. PIR benefits PIR panels are one of the better-performing insulants for commercial applications. It’s a solution that offers the best of both worlds, as it provides good compressive strength and a high thermal performance. Its use is ideal in a domestic or light commercial setting. Easy to handle and install, PIR panels reduce the risk of cold bridging by offering improved performance at floor junction details and perimeter upstands. Alternative choice As for alternative solutions, polystyrene-based insulation provides much higher load-bearing capacity, making it more suitable for use in a heavy industrialised setting. However, its compressive strength isn’t married to a strong thermal performance; hence PIR is the better all-round performer. PIR’s dual qualities also make for a more rapid, cost-effective installation. Its excellent thermal conductivity reduces the thickness and depth of a floor’s build-up, which in-turn decreases the amount of preparatory soil and rubble removal involved in new-build and refurbishment flooring applications. Eurothane® GP Recticel’s Eurothane® GP insulation board is a high-performance solution for a range of commercial and domestic projects involving floors, pitched roofs or framed walls. Lightweight and easy to cut, the board has an excellent thermal conductivity of 0.022W/mK, whilst its consistent tolerances, straight edges and flatness enhance its usability without compromise to durability. As far as flooring insulation is concerned, Eurothane® GP board meets the demand for longevity and good energy flow within a build-up. Specifiers shouldn’t stand for anything less. 

The UK urgently needs to decarbonise its grid, yet the cost of more sustainable supplies such as electricity will be untenable for the everyday bill payer writes Alex Hill, Managing Director at Whitecode. The technology is without question extremely promising, but how will the reality affect the general public? Will it further push consumers into greater fuel poverty? Is our green ambition just a dream? A report produced by the thinktank, Ember, revealed that renewable energy generated by wind, sunlight, water and wood constituted 42% of the UK’s electricity last year compared with 41% generated from gas and coal plants together. These findings are hugely encouraging if the UK is going to fulfil its aim to eliminate fossil fuel heating. The report represents quite a milestone and reassuringly suggests that we are weaning ourselves off unsustainable heat supplies. The war effort is clearly working, no doubt as a result of assistance from the UK government which has launched a series of schemes – including the Clean Heat Grant – to encourage homeowners to adopt renewable technologies. These schemes sit well with the ban of fossil fuel heating in new UK homes, which will come into effect in 2025. Whilst this all sounds highly encouraging and positive, the caveat is the cost. Air source heat pumps have been lobbied and heralded as the solution to cleaner heat, yet the financial burden of electricity will weigh heavy on consumers. When I started out as an engineer around 20 years ago the cost of electricity was 8p per kilowatt. Fast forward to 2021 and the amount peaks at 17p! In comparison, the price of gas hasn’t changed much at all and has remained at the cheap price of 3p. As a result of electricity’s high costs, we are seeing some homeowners receiving extortionate energy bills each month, sums well above the average running costs. Everyone is talking about going green and being carbon neutral, but what about fuel poverty? What are the solutions? If you have a gas boiler that runs cheaply in comparison; where is the incentive for you to change your boiler and supply? The ban on fossil fuel heating is solely for new homes and does not account for the existing stock. Some boiler manufacturers are exploring other options including hydrogen, which derives from water and has the potential to be very sustainable. It could be that this technology is another option to electricity. At the moment electricity is financially unviable for many consumers. Clearly there needs to be greater attention paid to this matter, and it would help to think laterally and in terms of longevity. In 15 years, a homeowner may have to upgrade their heat pump as they would do their boiler. A new boiler would cost you around £2000 in total, yet a heat pump comes in at around £5000 at least. This is with the proviso that there are a sufficient number of F Gas-qualified installers who are licensed to service heat pumps. Many boiler installers will need to upskill, and this may come at a higher cost both for installers and homeowners. In our pursuit to be green we must take a more holistic approach and account for every eventuality and ramification possible. On a separate note, the move towards electricity needs to be better funded. Whilst it is positive to see that we are steadily eliminating carbon-hungry fuel, someone has to pay for the decarbonisation on our national grid. At present the reality isn’t moving in tandem with the expectations, and if things remain unchanged, I fear it will push many into even deeper fuel poverty.
